Patent CA-2280972-A1 (CA)
Inventor: MENYUK CURTIS R
IPC: H04B10/18
Filed: 1998-02-13
Abstract: Des collisions entre solitons dans différents canaux de fréquences constituent une des sources principales d'erreurs dans des systèmes de transmission mettant en oeuvre le multiplexage par répartition en longueur d'onde (MRL). En outre, étant donné que les lignes de transmission classiques possèdent une amplification localisée, les champs de mélange à quatre ondes provenant des collisions de solitons augmentent de façon incontrôlable, ajoutant de l'amplitude et de la gigue temporelle à la gigue consécutive à la collision idéale de solitons. On résout ces problèmes en utilisant une carte de dispersion spécifique (100) servant à mettre en oeuvre une gestion de la dispersion et grâce à laquelle on peut réduire de manière importante la gigue temporelle induite par les collisions et améliorer les performances du système, même par comparaison avec les performances d'une fibre (40) à dispersion idéale décroissant de façon exponentielle.

Filed: 1998-05-29
Abstract: In a broadcasting satellite, signals transmitted through an up transmission line of a Ka band, which includes a plurality of communication channels, are received by a Ka-band antenna. The signals received by the antenna are passed through band-pass filters 12 to thereby extract a broadcasting signal transmitted through each communication channel. Those of the thus-extracted broadcasting signals, which have been transmitted through predetermined communication channels, are synthesized by each of synthesizers 15, then amplified by a corresponding one of high power amplifiers 16, and output to a corresponding one of a plurality of primary radiators 53 employed in an S-band antenna. The S-band antenna transmits each synthesized signal to a predetermined area that corresponds to a corresponding primary radiator 53. Thus, the system can be made to a simple structure, and the service area can be changed for each broadcasting signal.

Filed: 2000-04-04
Abstract: A 2-terminal solid state electrical switch is provided which can be connected in series with a load device in a the same manner as a conventional mechanical-contact switch, does not leak current during an "OFF" state, and operates from a dynamic pulse run mode during an "ON" state. The two-terminal solid state electrical switch of the present invention requires neither a power supply to operate, nor any mechanical movement and contact points. Consequently, no spark, arc or any mechanical noise is created in the solid state electrical switch's operation, nor does it corrode, thus allowing it to be used in a hostile environment. The solid state switch of the present invention can be put to uses not practical for conventional mechanical-contact switches, such as to control multi-appliances, as static circuit breakers, contactors and relays for fire-proof, explosion-proof, water-proof, anti-chemical, anti-corrosion, humidity resistant, dust resistant, anti-vibrations and heavy duty frequently operations. Further, a unique initialization circuit in the solid switch of the present invention resets the switch intelligently to a suitable operating mode after a power interruption, thus avoiding accidents that may endanger property and lives. The present invention also provides a highly isolated multi-point random remote control switch/relay suitable for wide industrial and other applications.

Patent CA-2305881-A1 (CA)
Inventor: LAMOUREUX NOEL
IPC: F16H55/54
Filed: 2000-04-19
Abstract: The evolution in the sphere of bicycle transmission is scant. From the beginning of the single speed driving spocket - driven spocket - and chain combination, the nearly one hundred year old Sturmey-Archer and the "derailleur" type of 1922 are the only transmission innovations to be accepted by the buying customer. The single speed transmission is evidently limited to flat or nearly flat country operation. The Sturmey-Archer planetary system, in the driven wheel hub, is limited to three and five speed ratios, limiting its hilly country operation. The "derailleur" type, using banks of ordinary sprocket gears on the driving and driven ends has a good range of available ratios.  However, it suffers from, A/ sharp misalignment of the driving chain in some of the chosen ratios, resulting in the chain skipping engagement and creating shocks, B/ required frequent maintenance of the cable operating system, lack of which may also creates the aforementioned problem.  Furthermore, study of all the available ratios on the "derailler" type of transmission shows that, only approximately half of the available ratios, when combining multiple gears in driving and driven wheel assemblies, generate a gradually usable range of speed and torque application. Another study, through observation of ordinary cyclist rallyes involving thousands of participants, showed an average of eighty per cent of competitors using the wrong ratio, leg muscles overworked or, uselessly revolving legs, pointing to the need of a simpler and better performing mechanical system. Study of available submissions on innovating transmission systems ( excepting the three already mentioned ) with manual operation or automatic changing of ratios, revealed some or all of the following shortcomings : cost of installed unit incompatible with normal bicycle retail prices -complicated mechanical and fragile elements - weather sensitive - complicated maintenance and repairs. The following specification, on the submitted variable speed transmission, addresses these desirable qualities, cited by priorities : fabrication cost and retail price compatible with the cheapest selling bicycles - simple mechanical parts and assemblies - easily repaired -maintenance-free - fully automatic and weatherproof.
